My invention relates to improvements in boilers, and has among its objects the production of. a boiler of the kind described which is compact, durable, reliable, efficient and satisfactory for 'use wherever found applicable. f

My 'nvention relates particularly to water tube boilers o f the inclined bent tube type and has for one of its objects to so arrange a superheater within the boiler that it will benormally inthe path of travel of the flames and heated gases from the combus- In the drawings, wherein likey reference characters'V indicate hke 'or corresponding parts,

Fig. 4 is a fragmentary plan view of thev underside of thev mud drum,`and

tially-on ythe line 5-5 of Fig. 4. l

Inv the drawings, wherein I have illus'- trated the preferred embodiment of `my in-A vention, l indicates any suitable type of setting adapted for use .by va water tube boiler having a plurality of water and steamv drums 2, 3 and 4 Varranged. horizontally therein at differing elevations, and a mud drum 5 below said steam drums and located between the bridge Vwallf of the furnace and the rear wall 7. The feed water is introduced into the drum 4 at 8, and the steam is withdrawn from said series of Y drums at the outlet 9 of the drum 4. y"Drums Fig. l is a sectional'view of a boiler. il-

by the bank of tubes 12,'the drums 3' and 4y by the banks of tubes A13, said last-mentioned tubes.' generally having superheated steam flowing therethrough, and the drums 4 and 5,- are connected by the bank lof, tubes 14.

ouY i Suitable arches, fire doors, nues, access doors,

etc., may be provided inthe boiler, but as these do not forma part of my present invention, no descriptionthereofis `deemed necessary.v l

vBaflles 16f-80-31 or their Vequivalents maybe arranged in theA boilerso asto direct the flames andthe 'heated gases fromy the combustion chamber l5"to, travel in a predetermined manner, said Vdirection normally taking the path of thefull line arrows shown vin Fig. 1.

',Adjacent thev bottom of the furnace and extending from adjacent the bridge wall 6 to the rear wall 7, I have Yarrangeda superheater, comprising a bankof U-shaped pipes or vtubes 18,l having headers 19 at one end. Oney of the headers is connected vby a conduit 20, so as to communicate with the outlet 9 of the steam 'drum 4, whereby thel steam will flow downwardly through the pipe 20 and throughthesuperheater in the direction shownV by the arrows, at -which.

point it maybe takenvofand deliveredto y preferably vin the Yform 'of a chambered Fig. 5 is a sectional view taken substan-A' receptacle engaging both the drum'f'and the top ofthe superheater, and in which the brick or 'the'like, so as not to becorneinjuredbythe bakingv of the mud and sediment in the drum and heat coming in contact therewith, and preventing the blow off connec4` tions from *burningk out. The rsuperheat'er operates substantially similar to any super heater, and in the particular location shown, while the same may, if desired be flooded when firing up the boiler, drained, blown off, etc., by virtue of its location, water therein or condensed therein when the boiler is cold will be turned to steam when the boiler is fired. j

From the foregoing description it will be seen that l have provided a boiler wherein the superheater is readily accessible and the superheating tubes are'so arranged'that they i will be normally inthe path *of the hot gases passing overthey bridge wall from the comustion chamber, thus superheating thesteam to a high degree. v Y (n Having thus described my invention, it is ,obvious that various immaterial modificatons may be 'made in the same without departing from the spirit of -my invention;
